I was hoping to catch a murmuration of starlings, but the very dull sky and me being a bit late, led to some mediocre shots. 
I was just putting the camera away when these low flying geese gave a semi impressionistic effect over the river. The patch of light is from a street lamp.
Goose trivia: a typical goose can eat up to two kilos of grass each day. Luckily, they don't usually visit the bathroom whilst in flight.
